Title: Theft resistant retail container
Inventor: GELARDI ANTHONY L
IPC: G11B33/04
Filed: 1988-05-25
Granted: 1992-10-20
Abstract: ABSTRACT OF THE DISCLOSURE    A one-piece retail container removably secures a substantially rigid item, such as a compact disc jewel box, in a securing well.  The retail container includes a vertically elongated frame forming sides, top and bottom of the retail container and a front plate, integrally formed with the frame, having front and rear surfaces.  The vertically elongated frame forms side and bottom walls of a securing well into which a first aperture of the front plate opens.  The front plate forms securing well ledges for restraining the substantially rigid item from passing through the front plate from the securing well.  Securing well tabs are integrally formed with the frame at the side and bottom walls of the securing wall for restraining the substantially rigid item from moving in a rearward direction, while a center rib is integrally formed on the rear surface of the front plate at the top of the securing well.  The frame, front plate and center rib are formed of a semirigid material which flexes in response to external pressure to permit the substantially rigid item to slide over the center rib and into and out of the securing well.  When the external force is removed, the frame, front plate and center rib substantially return to their original positions.  A display well may be formed at the top of the retail container with a second aperture of the front plate opening onto the display well, the display well removably securing a substantially planar flexible item, such as a recording album card, which is secured under the display well tabs.  A back card can be provided on the rear of the container for visual display of graphics and advertising at the back and at the top and bottom spline edges of the container.  The package is shrink-wrapped and user-friendly to consumers.

Title: Cooling system for heat insulating engine
Inventor: KAWAMURA HIDEO
IPC: F01P9/00
Filed: 1988-07-08
Granted: 1994-07-12
Abstract: ABSTRACT OF THE DISCLOSURE:         The upper parts of the cylinder liners and the cylinder head are formed integral in one piece, and a water jacket is provided around the outer peripheries of the upper parts of the cylinder walls, with no water jacket provided to the cylinder body.  This eliminates the use of the core for the water jacket in molding the cylinder body, which in turn reduces the engine weight, brings about a significant cost reduction and makes machining operations easy.  Because the piston head is made of a heat insulating material and a water jacket is not provided to the cylinder body, the heat is prevented from flowing down to the cylinder liners. Furthermore,  the cylinder liners are made of a ceramic material to improve an anti-galling characteristic during sliding motions at high temperatures.  Also, since the water jacket is provided only to the cylinder head, the water jacket can be made simple and small in structure, reducing the cooling water flow resistance.  This in turn permits the use of a small motor-powered water pump that  can be controlled  independently  of  the  engine  conditions. Moreover, since the cylinder body has no water jacket, there is a greater freedom in designing the cylinder body, which makes it possible to form reinforcement ribs on the cylinder body to increase its rigidity and thereby reduce vibrations and noise.

Title: Rail brace
Inventor: FARRELL ARTHUR W
IPC: E01B9/60
Filed: 1988-08-03
Granted: 1993-04-06
Abstract: ABSTRACT     A  rail  brace assembly for buttressing the head of  a  rail resting  on the top surface of a brace plate by engaging  fishing surfaces  formed on the head and base of the rail.   The assembly includes  a  rail  brace  having an  upper  slanted  surface  for engaging the head fishing surface,  a lower surface for  engaging the  base fishing surface,  a bottom surface adapted to rest upon the  brace  plate,  a front surface for receiving one  leg  of  a resilient  fastener and a pair of laterally extending ears.   The assembly  further includes a shoulder having laterally  extending side  surfaces  and an opening for receiving another leg  of  the resilient  fastener.   The  ears of the rail  brace  overlie  the laterally  extending  side  surfaces of the  support  to  prevent longitudinal  movement of the rail brace.  A resilient  fastener having  one  leg  adapted to engage the rail  brace  surface  and another leg adapted to be inserted into the shoulder opening acts to  apply a vertical downwardly directed force biasing the  brace against  the brace plate and a horizontal inwardly directed force biasing the brace against the rail to thereby prevent lateral and rotational movement of the rail brace.

Title: Particle agglomeration process
Inventor: HUDDLESTON DOUGLAS F
IPC: C22B1/244
Filed: 1989-01-18
Granted: 1995-02-14
Abstract: A  method  is  described  for  utilizing  metal containing by-products or waste products of metallurgical processes.    The  metal  containing  particles,  or  dust originating in metallurgical processes are agglomerated with a combustible agglomerating agent, and are usually charged to  smelters,  converters,  or  similar  high  temperature installations for the recovery valuable metals present in such  dust  particles.   The  agglomerates  are  obtained by mixing the dust particles  with  an  amount  of  combustible agglomerating agent.  The amount of agglomerating agent used for  producing  the  agglomerates is  related  to  the  bulk specific gravity and the particle size range of the dust particles.   The combustible  agglomerating  agent  of  this method, such as hydrocarbon wax, tar, bitumen, distillation, residue  and  similar  combustible  material,  is  solid  at ambient temperatures.         In  the  preferred  embodiement  the  combustible agglomerating agent is mixed with the dust particles at a temperature above the melting point  of  the  agglomerating agent, the hot mixture is subsequently allowed to cool in a mould and compacted.  The cooled compacts are removed from the  mould before  utilization.    In  a particular  form of application of this invention the mixture is allowed to cool in combustible containers and may subsequently be utilized as compacts bonded to their containers.         The  agglomerated  particles  may  be  used  for non-combusted purposes as well,  such as support structures or  filling  in  cavities,  or  merely  for  protecting  the environment  from  loose  dust  particles  of  metallurgical origin.
